tharitical of ball mill

The theoretical critical speed of a ball mill is the speed at which the centrifugal force is sufficiently large to cause a small particle to adhere to the shell interior for a full revolution of the mill The common range of mill speeds is 65 to 80 of critical depending on mill type size and the application
